DEV 330 - Developing Apache HBase Applications: Basics
Targeted towards data architects and application developers who have experience with Java, the goal of this course is to learn how to write HBase programs using Hadoop as a distributed NoSQL datastore. This first course in the HBase Java API series teaches the most important APIs for writing HBase programs, how to use the Java API to perform CRUD operations, use helper classes, create and delete tables, set and alter column family properties, and batch updates. Concepts are conveyed through lectures, hands-on labs and analysis of scenario.
This on-demand course is designed to be flexible to fit your schedule. Each lesson and quiz takes approximately 30 to 45 minutes to complete.
- Option 1: Complete the course in one session, approximately 90 to 120 minutes
- Option 2: Complete the course over a few days, 3 days of 30-45min/day
Lab activities take additional time and vary based on your system.
This course is part of the preparation for the MapR Certified HBase Developer (MCHDH) certification.
Lesson 1 - Java client API Part 1
- Define the CRUD operations from the Hbase Java API and discuss when and how to use them:
- Get, Put, Delete, Scan
- Describe the data flow between Client & Server when using these APIs
- Define the various helper classes for these APIs: KeyValue, Result, ResultScanner (Scan)
- Lab on Java Client API Get, Put, Delete, Scan: Use these APIs to create an application
Lesson 2 - Java API Part 2
- Client-side write buffer
- HTable Batch operations
- checkAndPut: atomic put operation
- KeyValue, Result Objects
- Atomic put with checkAndPut
- Lab on Java Client API HTable Batch, checkAndPut
- Use HTable Batch APIs in an application
- Use HTable checkAndPut APIs for row transactions in an application
Lesson 3 - Java Client API for Administrative Features
- HTable descriptor
- Lab create tables and define properties using the HBaseAdmin Java Interface
Prerequisites for Success in this Course
This course builds on DEV 320 and DEV 325 – Apache HBase Data Model and Schema Design, which gives the foundations of HBase architecture, the HBase data model, and schema design.
